(Cl. 2424-124) A This' inventionrelates to a head for a beam upon which yarn is wound. Beam heads areIsubjected tothe outward pressure fof yarn wound'. on the beam. Thetendency has been to provide larger sizes of beam heads than heretofore,thereby increasing'pi'essure on the beam head, tending to move the headalong the beam. Should the head move along the beam, the yarn thenbecomes snarled, and serious diicultiesresult.; Further, thequestion-,jof support of the head against bending outwardly due to` theincreased pressures' andleverag'e developed through larger beam headspresentsdiiiiculties vin supporting the head against exur'e.

.One of the 'objects of this invention is to provide a better holding ofthe hub of the'head in position on the beam.

vAnother object of the invention is to better distribute the pressuresused for binding the hub on the beam.

Another object of the invention is to apply binding pressure on the hubat a point closely adjacent the point of embracing contraction so that amaximum value of the pressure applied may be obtained for binding thehub in position.

Another object of the invention is to increase the exure of the arcuateportion of the hub so that it may better wrap about the beam for holdingthe head in position.

With these and other objects in view, the invention consists of certainnovel features of construction as will be more fully described andparticularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is an end view of the beam head as mounted upon a beam;

Figure 2 is an elevational View of the beam and beam head partly brokenaway;

Figure 3 is a section on substantially line 3--3 of Figure 2 and on amuch larger scale;

Figure 4 is a perspective view of one of the sections of the hub;

Figure 5 is a plan view on an enlarged scale of the shoe through whichpressure is applied for contracting the hub.

In proceeding with this invention, I have provided a plurality ofsections of a hub and place them in edgewise contact with the plate ofthe head in such a relation that they are movable relative thereto. Eachof the sections is arched so that together they will embrace the beam,and for contracting the embracing size of the hub sections, shoes areprovided through which pressure may be applied at the juncture of thearcuate portion of the hub and outwardly extending arms leading fromthese arcuate portions so that contracting pressure may beadvantageously located at the juncture of the arcuate portion andoutwardly extending arms, and further, I have reduced the cross sectionof the arcuate portions intermediate the location of the arms so thatthe arcuate portion may 2,744,695 Patented May 8, 1956 ICC 2 better wraparound and bind the beam as contraction takes place.

With reference to the drawings, 10 designates a beam such for instanceas a warp beam upon which yarn or thread is wound, which is providedwith heads at or adjacent its opposite ends, which are adjustabletherealong. One of such heads is herein shown designated 11 and theother headl will be identical therewith.- This head 11 comprises a plate12 v'which is rolled outwardly at its peripheral edge as at 13 and isprovided with a central aperture 14 to receive the beam 10 therethrough.A hub is mounted on the outer surface of this plate 12 and is designatedgenerally 15. This hub comprises a plurality of sections 16, which inthe present instance is shown as four sections. j t

Each hub section comprises anarcuate portion 17 having a relativelyshort outwardly extending arm 18 and a longer outwardly extending arm19. The sections arev held in edgewise relation against the plate 12 bymeans of I v-sfhaped brackets 20 having one arm 21 welded to theouterface of the plate 12, while the other arm 22 extends outwardly from theplate and carries a pin 23 which projects through the opening 24 in thearm 19 and is headed 'over as at 25 against the arm 22 and headed overas at 26 to engage the surface of the arm 19 about the opening 24. Thispin with its head is arranged so that the arm may move radiallyoutwardly of the head while the edge of the arm 19 maintains itssupporting contact with the plate 12. The inner Aarcuate surfaces of theportion 17 lare such that the several sections together embrace the beamso 'that when contracted, they will grip the beam and prevent the headfrom sliding therealong.

Each of the arms 18 is clapped inwardly to provide a projection 27 onthe inner surface of the arm 18 with a recess 28 on the outer surface ofthe arm- 18, while each of the longer arms 19 is provided with a similardap to form a projection 29 on the inner surface of the arm and a recess30 in the outer surface of the arm. The projections 27 and 29 arelocated at substantially the same radial distance from the axis of thebeam when the sections are in assembled relation so that the projection27 of the short arm 18 will contact the projection 29 of the longer arm19 of the next section. Thus, these arms contact at a point spacedoutwardly from their arcuate portions 17.

In order to apply contracting pressure on the arms, there are providedidentical shoes designated 31, there being a shoe 31 against the arm 18and a duplicate shoe 31' against the arm 19. One of these shoes is shownby itself in Figure 5 in plan view, which shows a generally triangularconfiguration from which there projects a fulcrum foot 32 and twopressure feet 33. The fulcrum foot 32 islocated in the recess 28, whilethe pressure feet 33 fit in the juncture 34 between the arm 1S and thearcuate portion 17 of the section. There being two of these feet, onewill be located at each edge of the arm 18 at this juncture. The shoealso is provided with openings 35, the center of which is on a linebetween the center of the fulcrum foot 32 and the fulcrum foot 33 asshown by center lines 36, which will thus place the two openings oneither side of the center of the shoe and in balanced relationtherewith. These openings 35 register with openings 37, 38 in the arm 18and with similar openings 39 and 40 in the arm 19 of the adjacent clampsection. A similar shoe 31 engages arm' 19 in the same manner justdescribed. Bolts 41 extend through the registering openings of the shoesand arms and are provided with heads 42 to engage one of the shoes, anda nut 43 is threaded on to the threaded end 44 of the other end of thebolt, which through a washer 45 may be used for applying pressure on theshoes.

It will be seen that whenv pressure is applied through theV bolts 41, ifVthe arms 18 and 19 as shown in Figure 3 are not in contact, they willV`move into contact at the locations 27, 29 and then furtherL pressurewill tend to swing tbe. cbeee. each. abetlt ite.
